Boss OC-3 Snapped Level Knob

Recommended Posts

I bought this pedal a while back and loved it. I can't remember how, but the level knob snapped. Have a look:




Where can I get a replacement? Presumably it's a logarithmic pot, so I'll have to get a precise replacement.

I still have the snapped off part handy.

Any ideas?

EDIT - Apologies for posting in the wrong forum.

The 50k log likes the fella, but you'll need to check the otherside to see how the pins mount onto the pcb, and check the measurements against yours, just to be sure.

It's not a bad idea. If you get the glue to stay in the centre, you should be able to attach any shaft you want and turn the pot.

Cheers for the replies chaps!

I thought of glue, but I'm not exactly sure whether I could get the snapped piece in the right place.

I think I'll go ahead and buy a pot. My housemate is very good at electronics, so I'm sure he'll be able to help.

P.S. Bobbass - you have no idea how long I googled for this little spare part!

I'm having a bit of trouble. These guys don't have any of those in stock, and won't have for a long while. I still searching around, but is there anywhere else I cn look? Is there a specific thing I need to search for?

I have indeed, but they don't have the correct ones. I'm currently looking at this website:

[url="http://uk.farnell.com"]http://uk.farnell.com[/url]

But I'm not 100% sure on what specifications I need.

EDIT: Is [url="http://uk.farnell.com/vishay-spectrol/248-7-10-50k/potentiometer-50k/dp/9609563"]this[/url] more what I looking for?

This may sound a bit ordinary, but have you tried asking Roland? If anyone has the direct replacement or can get one shipped from the factory, then they're the folks! A busy place, so don't panic if no reply immediately.

Ha! Funny how these things never occur to people. Good suggestion. I'll get on it.

Cheers.

Not quite.

Hubrad's advice of contacting Roland directly got me a reply from a chap called Steve who could get me the exact part for £3.45. Although I'm not sure whether that's with postage.

Haven't done it quite yet...

[quote name='Toasted' post='411921' date='Feb 17 2009, 12:49 PM']That sounds expensive for a pot, BUT if it's exactly what you want and makes your pedal work again, sounds bargainous.[/quote]
Give something a Purpose, especially a Very Important Purpose, and the price skyrockets!
At least this will be the exact fit and value.
